MACHINE FOR SPIRALLY WLNDING A STRIP OF WOOD.

BPECIFICATION forming part of Letters Patent No. 323,699, dated August 4, 1885.

Application filed April 13, 1885. (No model.)

To aZZ whom it may concern.-

Be it known that 1, JAMES MACFARLANE, of Malden, in the county of Middlesex, of the Commonwealth of Massachusetts, have i11- vented a new and useful Improvement in Machinery for Spirally \Vinding a Strip of food for Converting it into a Cylinder; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which Figure 1 is a top view, Fig. 2 a front elevation, and Fig. 3 an end view, of a machine embodying my invention, the nature of which is defined in the claims hereinafter presented. Fig. 4 is a transverse section taken on the line A B of Fig. 1. Fig. 5 is a longitudinal section of the cylinder D, hereinafter described.

In such drawings, the frame of the machine is shown at 0. Above the said frame is a hollow cylinder or drum, D, whose neck a is supported in suitable boxes, I) b, such neck being a tubular spindle having at its outer end a stuffing-bomb, to receive and revolve on an induction-pipe, d. The cylinder,at its opposite end from which the said neck projects, is unsupported, in order that after a strip or strips of wood or other material may have been wound on it such strip or strips may be drawn off it endwise thereof. Steam is to be let into the cylinder through the pipe (1, such being to keep the cylinder in a heated state while the strip is being wound on it. By having the cylinder so heated the strip which in being applied to the said cylinder is to be soft and yielding by having been steamed, becomes more or less desiccated, and its coils set while it is being wound in a spiral about the cylinder.

Concentrically on the neck of the cylinder D there is fixed a gear, 6, that by means of an intervening gear, f, engages. with a pinion, g, fixed on a drivingshaft, h, provided with a fast pulley, i, and a loose pulley k. Furthermore, there is secured on the neck a another spur-gear, Z, aside of which and fulcrumed on the said neck is a lever, m. This lever has, on a journal, at, projecting from its shorter arm, two gears, o and p, that are fastened or connected so as to revolve together, the smaller of them engaging with the gear I. Above the larger of the said gears isa lever, q,

that is fulcrumed on the shaft of a long screw, F. To the lower arm of such lever there are pivoted two gears, r and s, that engage with each other. One of them-win, that marked s-'engages with a gear, t, fixed on the shaft of the said screw.

There extends upward from the inner box, I), a sector, a. Between stops 2) v at the ends of its are the upper arm of the lever q can be moved from one to the other of such stops to carry one or the other of the two gears 11 and 8 into engagement with the longer of the two gears 0 and p, in order to cause the screw to be revolved in either direction. There is a bolt, w, arranged in the upper arm of the lever q to engage with either of three holes, as ye, made in the sector, such bolt being provided with a lever, a, for retracting it by manual power, a spring, I), applied to the two levers serving to impel the bolt forward. WVhen the bolt is in the median hole, y, both of the gears r and s will be out of engagement with the larger of the two gears 0 and 19. So when the bolt is in either of the other holes, so or 2, one of the gears r and s will beheld by it in engagement with such. larger gear.

The screw F, arranged in front of and somewhat above the cylinder D, has its journals supported in suitable bearings,c, in standards (1, erected on the frame 0.

Screwed on the screw is a nut, G, provided with an arm, (1 that extends from it and slides on a stationary guide-rod, H, arranged in front of and in parallelism with the screw. From the under side of the nut there projects an eye or staple, 0. (Shown in dotted lines in Fig. 2.)

On the driving-shaft being put in revolir tion the cylinder D and the screw F will be revolved, and as a consequence the screw-nut will be caused to move along upon the screw lengthwise of the latter.

The purpose of the lever m is to enable gears of proper sizes to be used on the journal of the lever as the width of the strips to be wound may from time to time require for the screw to be revolved at the right speed for the winding to be suitably effected. By turning the lever on its fulcrum the gears after having been placed on the 'journafofwhe lever,

TOD

may be borne upward so as to put the larger of them into engagement with the gear directly overit. In the longer arm of the lever is a slot, f, to receive astationary clamp-screw, 9, that goes through the slot and is provided with a nut, h, to clamp the lever in position.

If we suppose a strip of wood of uniform width and thickness to be inserted lengthwise through the eye e, when such eye is at or near one end of the cylinder D, and to be extended from the said eye to and be clamped to. the cylinder, and the cylinder and screw to be revolved at suitable velocities, such strip will be wound in a spiral on the eylinder, with each coil of the spiral in close contact with the next one, and after the strip may have been wound in one direction on the cylinder, if we reverse the motion of the screw,the strip will be coiled on the part previously wound. The coils of one spiral may be caused to break joints with those of the other.

Previous to the strip of wood being wound on the cylinder D such strip should be steamed so as to soften it and render it properly flexile, it being in such a condition while being wound on the cylinder.

With the above described machine strips of ash or other proper wood can be wound in spirals, with one spiral about another,whereby tubes for conversion into articles of various kinds-such as roving cans or pails, for instance-may be produced.

I claim 1. The combination of the hollow cylinder provided with lllCOhtLlllSIli 'l'or revolving it,and supported at one end only by a tubular neck and bearings, as described, with the guide-nut and its supporting wire and rod, and with the screw arranged with such nut and cylinder, and provided with mechanism for imparting rotary motion to it in either direction, as specified, the said screw, nut, supportingrod, and hollow cylinder being arranged parallel with each other, as represented.

2. The combination of the cylinder D and the screw F with the mechanism substantially as described for revolving the screw in either direction by the cylinder while being revolved, such mechanism consisting of the gear Z and the two levers m and q, and their gears 0 p r s, and the gear 26, the latter gear be ing fixed on the shaft of the said screw, and the gear Z being fastened on the neck ol. the cylinder, and all being arranged and to operate substantially as set forth.
